The use of genetic engineering can only benefit humans.

Extracts from this document...


BY Johnathan Lamb Yr 12 The use of genetic engineering can only benefit humans Genetic engineering is a word that is used to describe the ability that has been developed enabling molecular biologists to move genes from one chromosome to another. In recent years, scientists have learned new techniques to get at the DNA and, therefore, the genes of organisms. They have learned how to isolate individual genes from a DNA molecule and to transfer them from one kind of organism to another. The ability to change the genetic instructions of an organism has opened the door to many new discoveries, many of which are expected to benefit humans. For example, some rare and expensive disease-fighting hormones can be manufactured in the laboratory using organisms. Some plants and animals that are used for food can be genetically altered to make them easier to grow or more nutritious. Microorganisms that engulf and break down toxic waste materials can be developed. We likely will learn many other possibilities as we learn more about DNA and how the cell functions. ...read more.


With this system the human being is producing a protein inside of them, which will provide them constantly with enough insulin thus meaning that they don't need to constantly take injections. This is not only saving the person with this defected time but will also make them physically and mentally more confident in what they do. This type of engineering can also create a new type of human being with advantageous traits that will help us as mammals move along the evolution chain. It is also very dangerous because there is a risk of mutation from trans-species transfer of "jumping genes," this means that the risk of mutation would be from the gene and mutate the body into whatever organism the gene came from. There could be the creation of super viruses by viral recombination in human cells, and there could be cancer genes that recombine with endogenous viruses that make them resistant to the normal treatment we have now. People also disagree with genetic engineering because of moral and/or religious beliefs since God created us and if we engineered human beings people would then think that they could play the role of God. ...read more.


If modifications go wrong there might be a heavy dependence on herbicides, contamination of organic crops with transgenes from other genetically modified crops. Microorganisms are also beneficial since they can produce pharmaceuticals that cannot be produced any other way, it can get rid of contaminants easily, and cleans up waste pollution. The disadvantages are that it can produce dangerous pathogens and diseases, which may escape containment, a spread of antibiotic resistance to anything so it would be dangerous to us, and a recombination of supposedly crippled viruses. (www.anth.org/ifgene/beginner.htm) Another disadvantage is that it could be dangerous to the environment when considering a genetically manipulated organism could cross with other organisms. This could cause unpredictable and irreversible changes to the ecosystem. However nobody will know what will happen. This is the reason why so many people have an opinion that genetic manipulation should be forbidden. I think that genetic engineering is beneficial to humans, plants, animals, and microorganisms because it allows all of us to reach our potential in life and it is also a horrific concept because we would be playing the role of God since we can make and destroy organisms when ever we want. ...read more.
